I tried to configure it on the Video Card "configure" during installation. The tests were sometimes "out of range" and sometimes ok. Even when it was ok, after the first reboot and a nice "linux teaser" 10 minutes session, after a second rebooting the command line "log in" screen appeared again! (and I don´t know even a single command!) The grafical interface is gone!! Sometimes right over install, sometimes after at the third boot.

How can I fix it? Installing again, right? Why does the grafical interface didn´t loaded as default, even when correctly set? (and if i'm right) How do I KNOW AND SET the correct screen resolution, refresh rates and color depth?
